I still think it will be a good idea to add a link to the forum on http://reverent.org/bad_painting_contest.html

No, it is not. If you look at the url of this page it has t=555 in it. This means that this topic is number 555. There are, however, only 51 topics in the forum. 504 topics were spam which I deleted. If I add a link from the contest page there will be even more spam.
